I plan, with the help of you all, to map RDR2's world based on screenshots and footage. We did it with GTA V and it turned out pretty accurate. Let's do it again! It's still too early to tell, and i might be barking up the wrong tree. But i have to start somewhere...
And if we were to include that "leaked map", id' say it's somewhere in the heartlands. Although the river looks a lot more twisty, more like the one to the right of the map if i'm honest.

I just figured out how to get into the glacial fractures safely, and explore them! I'm like the first man in the moon! 😂 Also, I'm talking about the deep abyss crevasses, not the shallow ones. There are paths and cavern-like structures down there.
So I did a step-by-step guide, in case anyone else wants to check these out for themselves.

So this was weird. I've crossed through the Tree's of Guarma many times, and only now I see this huge cube randomly. It is only visible if in range, so you wouldn't know it was there unless you were close. It was hollow and untextured. I have seen many other small cubes around outside of the map, and i assumed they were skyboxes for lighting. But this box was insanely large lol

Nope, didn't need any horse items crossing the river. The stamina stimulants were mainly for speeding up the journey on the cheat horse. So, at 3:20 you can drop off the edge, die and respawn in Guarma, but you can't use any cheats there. So option 2 is if you want to ride around instead of walk everywhere once there.
Strangely though, you can whistle your horse in RDO whilst in Guarma, just not in story mode.

😂 I did show you though. He's just a dumb ass, and needs his hand held all they way through.
Yeah i can understand the other map areas being there for visual standards, but this one you would never see unless you went out of your way. They clearly had big plans for Guarma and cut back fairly early on.

So I went exploring around Guarma, I've done it a few times now. But I always avoided the low poly zones, fearing I would fall through and kill my character, sending him back into the playable area. Now after exploring multiple times, I decided to leave no rock unturned and took the leap of faith.
I soon realized that, after galloping around a large distance, that the entire low poly segment was solid ground. So I decided to go further, and see how far those low poly models go. To my surprise, Guarma is, in fact, an entirely handcrafted island, with shores, beaches, bays, and even painted on pathways! So my first thought was this must the entire Island cut from the leaked map? At which point I decided to walk the entire island.
It took me several in-game days, since I lost my horse down the side of a cliff very early into my expedition, and had to walk it on foot. Interestingly I started to sum up the shape of the island, and the inner mountainous features, and it does in fact match that leaked map island! I noticed Cinco Torres was that small island to the south west of the island, but in the story, the fort had been placed into the bay. Exploring in that direction, I found an island offshore! This can't be a coincidence, it all fits into place, like missing puzzle pieces.
So the big question at this point is, why did they cut the content? The map is clearly early development, but they crafted it, and even names added on the leaked map if different locations lead to pathways and square pixel patches which may represent buildings. The island is also big, they could have cut it down, so save memory, yet they left it there like some extremely large easter egg. It blew my mind!
So I'm currently compiling the video, although it's very dull watching me walking around a huge empty island, I know that the mapper in you will appreciate it!
I'll post that later,
Discuss!
The island in context:
I never thought I'd be mapping Guarma! lmao...

New methods have been found, so my journey continues!
One place that has really baffled me is Tempest Rim. It's a big chunk of the map within the world boundaries yet it's entirely unreachable from every angle. So my next expedition is focused on just that. Looking around that whole area and beyond.
Next Stop, Guarma!
The main event. Took me hours of exploration, and editing. Still ended up being 45 minutes long!
I also made a montage of all the highest peaks I could get to, outside of the playable map.

I haven't seen many people explore beyond the boundaries really, apart from Mexico, so I decided to create a small exploration series to show off how much land there actually is, outside of the main map.
More to come.
